              Reworked template caching mechanism for radically improved
              concurrent performance, with help from Azul Systems engineers.
              (Achieved 20x speedup with Struts2 webapps on a 128-CPU Azul
              device compared to 2.3.12.) Also, template loading (including
              parsing) errors are now cached, improving performance in
              applications that often try to get missing templates.</p>
